BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an in-vehicle apparatus and a control method of an in-vehicle apparatus, and is applicable to, for example, a multimedia terminal having a function of navigation equipment and a function of video playback. The present invention aims at improving usability to a user in a case of accepting operations through a touch panel and a remote commander, by switching and displaying a touch panel menu screen suitable for operation through the touch panel, and a remote commander menu screen suitable for operation through the remote commander, in order to accept operations of the user.

2. Description of Related Art

Traditionally, in car navigation equipment that is an in-vehicle apparatus, a technique disclosed, for example, in Japanese Patent Application Publication Laid-Open No. Hei 10-141974 is applied so that menus are displayed in a hierarchical structure, and selection of the menus is accepted through a touch panel, thereby accepting operations of a user. In the car navigation equipment, the selection of the menus in the hierarchical structure is also acceptable by the operation of a remote commander, so that it is able to operate the equipment through the remote commander, while the equipment is mainly operated through the touch panel.

In a monitor unit relating to video, such as a television receiver and the like, it is configured to accept switching of display objects by the operation of operators disposed on a control panel, and by the operation of a remote commander. Herein, “operator” in the present specification means elements used for inputting operation instruction, such as a button, a key, a dial and the like.

By way of contrast, there has recently been proposed an in-vehicle apparatus having the navigation function and the video regeneration function as described above. Also in this in-vehicle apparatus, various operations of user are considered to be accepted by the operation of a touch panel and the operation of a remote commander.

However, in this in-vehicle apparatus, there is a problem that merely integrating conventional car navigation equipment and a user interface relating to a monitor unit degrades usability of the equipment.

Thus, the operation through the touch panel has an advantage that a desired menu is quickly selectable because a desired menu can be selected with a number of menus displayed. However, there is a disadvantage that attention for safety is required in an application to an in-vehicle apparatus, because at the time of operation, it is necessary to turn the eyes toward a screen and watch the menus.

On the other hand, in the operation of the remote commander, it is able to operate by blind touch by assigning a dedicated function to each of the operators of the remote commander. Thereby, in an application to a car audio system, the burden of operation can be reduced than the operation through the touch panel. However, when selecting the menu in the hierarchical structure, as in the car navigation equipment, it becomes necessary to ultimately operate by tracking a display relating to the operation of the touch panel. In this case, there is a disadvantage that operability deteriorates remarkably than the operation of the touch panel.

Thereby, the in-vehicle apparatus 1 is configured so as to execute switching of operations, and the like, by the operations of the operators 13P to 18P disposed on the side of the display screen 11, or the operation of the touch panel 39 disposed on the display screen 11, or the operation of the remote commander 40.

(1-2) Remote Commander

FIG. 3A and FIG. 3B are a plan view and a side view showing the remote commander 40. The remote commander 40 is formed in an elongate plate shape having a predetermined thickness, and has on one end face of the shorter-side thereof a light-sending unit 41S for outputting remote control signals by means of infrared ray. In the remote commander 40, on the left side of the upper side surface than the side on which the light-sending unit 41S is disposed, there is disposed an operator 42 composed of a seesaw switch used for switching between zoom-out and zoom-in in displaying maps. A joystick 43 that is a press-operable pointing device is disposed in the proximity of the operator 42. On the right side of the joystick 43, a display operator 16R, and a map operator 17R are disposed upward and downward directions, respectively. On the front side from these controllers, a current position operator 44 for instructing the display of the current position is formed horizontally. Thus in the remote commander 40, the operators 42, 43, 44, relating to navigation are collectively disposed in the proximity of the map operator 17R.

Further, in the remote commander 40, a program operator 14R and a menu operator 15R are disposed on the front side of the current position operator 44. A jog dial (hereinafter referred to as a “center jog”) that is a press-operable rotational operator is disposed at the center of further front side, and a back operator 48 and a forward operator 47 are disposed on the left and right of the center jog 46. Thus, these operators 14R, 15R, 46 to 48 are operators relating to the menus displayed on the display screen 11, so that the operators relating to the menus are collectively disposed in this preferred embodiment.

In the remote commander 40, a cover 49 is disposed on a further near side of the center jog 46. The cover 49 opens to a front side. It is constructed such that an operator 50 comprising a plurality of keys relating to character input and numeric input such as numerical keypad, a clear key, etc. can be operated by opening the cover 49.

Further, on one side surface of the remote commander 40, a source operator 13R, a jog dial (hereinafter referred to as a “side jog”) 52, which is a rotary operator that can be pressed, a back operator 53, and a source-off operator 54 are disposed from top to bottom. These operators 13R, and 52 to 54 are operators relating to playing back of audio video, that is, the operators relating to operations, possibly operated by so-called blind touch. Thus, the usability of the remote commander 40 can be improved by collectively disposing these operators 13R and 52 to 54 on one side surface.

In response to the operations of these operators, the controller 33 (FIG. 2) executes a program recorded in the hard disk drive 35, thereby executing navigation processing and also providing various contents to the user, in response to the operations by the user.

Alternatively, when a user instructs viewing of video content recorded in the hard disk drive 35, the controller 33 instructs the hard disk drive 35 to play a file relating to the video content, and provides video data and audio data outputted from the hard disk drive 35 to the user, as in the case of receiving television broadcasts. Alternatively, when the user instructs playback of music content recorded in the hard disk drive 35, the controller 33 similarly instructs the hard disk drive 35 to play the music content, and causes the output unit 27 to output audio data outputted from the hard disk drive 35. If during these processing, the user instructs switching of the content as a playback target, the controller 33 changes the file read from the hard disk drive 35 to repeat similar processing.

Alternatively, when the user instructs display of a map, current position information is obtained from the GPS unit 22, and map data recorded in the hard disk drive 35 is loaded with reference to the current position information. In addition, based on the loaded map data, a map is displayed on the display unit 37.

Alternatively, when viewing and listening of content relating to AUX input is instructed, the controller 33 controls via the interface 26 the operation of the optical disc drive 24 to obtain data relating to video content and music content outputted from the optical disc drive 24. In addition, the obtained data of the video content and the music content are processed in respective units to provide these contents to the user. Further, based on the instruction of the user, the content so obtained are recorded in the hard disk drive 35.

Alternatively, when browsing of the Internet is instructed, the controller 33 activates a browser software to connect the Internet through the communication unit 34, and displays video and the like obtained through the communication unit 34 on the display unit 37, and outputs voice data from the output unit 27. Alternatively, when processing relating to electronic mails is instructed, the controller 33 activates a mailer software to display on the display unit 37 electronic mails held in the hard disk drive 35, and obtains via the communication unit 34 the electronic mails to be displayed. In addition, the controller 33 accepts the input of electronic mail by the user, and sends this electronic mail via the communication unit 34.

Alternatively, when viewing of a still image is instructed, the controller 33 obtains a still image file of a processing target by accessing to the memory card 32 via the interface 31, or accessing to the hard disk drive 35, and displays a still image relating to this still image file on the display unit 37. In addition, on the basis of the instruction of the user, the controller 33 inputs and outputs this still image file between the memory card 32 and the hard disk drive 35, or deletes it from the record of the memory card 32 and the hard disk drive 35.

Alternatively, when the user instructs navigation processing, the controller 33 accepts the input such as destination and the like by the user, and obtains the current position information from the GPS unit 22, and then executes route search processing, on the basis of this information. In response to the setting made by the user, the controller 33 outputs various information so as to perform route guide of the user on the basis of the route so detected.

The controller 33 executes these processing by executing a program recorded in the hard disk drive 35. When the user presses the power switch 12 to turn off the power of the in-vehicle apparatus 1, the controller 33 records and holds the state at the time of power-off. Alternatively, the power is turned on by the operation of the power switch 12, or by press-operation of the joystick 43 in the remote commander 40 so that the recorded and held state during the power fall is reproduced.

(1-3) Processing by Controller

FIG. 4 is a plan view showing a touch panel program menu screen that is displayed on the display screen 11 by the control of the controller 33. Here, this touch panel program menu screen is a menu screen suitable for operation through the touch panel 39. In this preferred embodiment, it is configured to also prepare a remote commander program menu screen that accomplishes the same function as the touch panel program menu screen and is suitable for the operation through the remote commander 40. The controller 33 displays the touch panel program menu screen in a case where it can be judged that the operation of user instructing the display of this program menu screen is intended for the operation through the touch panel 39.

Specifically, if the program operator 14P disposed on the control panel of the in-vehicle apparatus 1 is operated, or in a case where the menu to go backward is selected through the touch panel 39 on the display screen relating to a lower hierarchy of this program menu screen, or further, in a case where the operation by the user on a portion other than the menus is detected in a state of displaying the program menu screen relating to the remote commander, which will be described later, the controller 33 displays the touch panel program menu screen.

Here, the program menu screen is a main menu screen relating to selection of content to be provided to the user, and the like, and is formed by displaying a menu of selectable applications in the in-vehicle apparatus 1. Here, as a program menu screen, there are displayed a TV menu M1 to instruct receiving of television broadcasts, a video menu M2 to instruct playback of video content recorded in the hard disk drive 35, an audio menu M3 to instruct playback of music content recorded in the hard disk drive 35, a map menu M4 to instruct display of a map, an AUX menu M5 to instruct playback of contents relating to AUX input, a WEB menu M6 to instruct activation of a browser relating to the Internet, a mail menu M7 to instruct processing relating to electronic mails, and a photo menu M8 to instruct processing of a still image. There is also displayed a menu M11 to back to the state immediately before this program menu screen.

On this program menu screen, among these menus M1 to M8 and M11, the menus M1 to M8 relating to the selection of applications have the same size. Since none of the menus M1 to M8 is provided with a cursor or the like indicating a focus, they are aligned and displayed. This has user percept that any of these menus M1 to M8 can be selected by the operation of the touch panel 39. Thereby, if any one of the menus M1 to M8 on this program menu screen is selected by the operation of the touch panel 39, the controller 33 controls the entire operation so as to execute the corresponding processing.

If the back menu M11 is selected and operated with this program menu screen displayed, the display screen is switched to the last display. On the other hand, if the center jog 46 of the remote commander 40 is operated with this program menu screen displayed, the display screen is switched to the remote commander program menu screen.

Meanwhile, FIG. 5 is a plan view showing the remote commander program menu screen. The controller 33 displays this remote commander program menu screen when it can be judged that the operation of the user instructing the display of this program menu screen is intended for the operation through the remote commander 40.

Specifically, if the program operator 14R disposed at the remote commander 40 is operated in the state of providing content to user, and the like, or if the back operator 48 of the remote commander 40 is operated in the state of displaying a display screen relating to a lower hierarchy of this program menu, the controller 33 displays this remote commander program menu screen. In addition, as described above, it also displays this remote commander program menu screen when the center jog 46 is operated in the state of displaying the touch panel program menu screen.

Here, this remote commander program menu screen is formed by displaying a menu of applications selectable with the in-vehicle apparatus 1, as in the program menu screen relating to the operation of the touch panel. Further, menus M1R to M8R of respective application programs are displayed by the same design as the program menu screen relating to the operation of the touch panel 39. Thereby, in the in-vehicle apparatus 1, menu screens are switched so as to reliably select a desired application.

Therefore, on this program menu screen relating to the operation of the remote commander 40, the controller 33 is configured to display as to which application can be selected immediately, together with other selectable menus.

Thus, if the center jog 46 disposed at the remote commander 40 is rotationally operated in the state of displaying this program menu screen relating to the operation of the remote commander 40, the controller 33 rotates the display position of the menus M1R to M8R in response to the direction of rotation of the center jog 46, as indicated by an arrow A, and also changes the size of the respective menus M1R to M8R so as to correspond to the rotation of the display position. Thereby, the focus of a menu can be switched in response to the user's operation of the remote commander 40. Alternatively, if the center jog 46 is further press-operated, or if the forward controller 47 of the remote commander 40 is operated, the controller 33 controls the entire operation so as to execute the application relating to a focused menu (for example, in FIG. 5, the menu located at the leftmost).

If one of the menus M1R to M8R is selected by the operation of the touch panel 39 on this remote commander program menu screen, the controller 33 controls the entire operation so as to execute the application relating to the menu selected in response to the selection of the menus. On the other hand, if the operation on a portion other than the menus M1R to M8R is detected with the touch panel 39, the display is switched to the touch panel program menu screen.

FIG. 6A is a plan view showing a main display screen relating to the menu M2 displayed in accordance with the instruction as described above. In this case, the controller 33 displays the image of content at an area except for a strip portion on the lower side of the display screen. At this time, the controller 33 records and holds the file relating to the menu M2 played back last time, and the played back status of this file and the like (so-called last memory). In accordance with this record, the controller 33 plays back and provides the user the corresponding content from the position at which playback is suspended. Thereby, the in-vehicle apparatus 1 is configured so as to easily view desired content from the position at which the last viewing is suspended.

On the other hand, various menus relating to this application are displayed at a strip region in a lower end of this display screen, together with information related to the image that is being displayed. Hereinafter, this strip display is called “control bar”. Specifically, an OFF menu M21 for instructing termination of this application, which also functions as a back menu, is displayed on the leftmost of a control bar B1. The controller 33 causes this application to be terminated by the operation of the OFF menu M21 through the touch panel 39, and switches the display to the touch panel program menu screen. Subsequently, a title, which is attribute information of the content being displayed, is displayed at the control bar B1. Here, if the length of this title is longer than the length of the region for displaying the title, the controller 33 displays the title by scroll. Subsequently, various operation menus are displayed by right justification at the control bar B1.

Here, a rewind menu M22, a back-to-previous-chapter menu M23, a playback/pause switching menu M24, an forward-to-next-chapter menu M25, a fast forward menu M26, a list display menu M27, a switching menu M28 for switching display/non-display of the control bar B1 are displayed in sequence on this operation menu. When the operation of each of these menus is detected by the operation of the touch panel 39, the controller 33 controls the operations of respective units so as to correspond to the operation by the user.

Alternatively, when the center jog 46 of the remote commander 40 is operated with the control bar B1 so displayed, or in a case where the display is switched to a display screen relating to the menu M1 by the operation of the remote commander 40, the controller 33 displays a cursor on one of the menus M21 to M28 by means of a bounding box, and displays the menu focused by this cursor. Further, the controller 33 switches focuses in sequence among the menus M21 to M28 by moving in sequence this cursor by the rotational operation of the center jog 46. In addition, by the press-operation of the center jog 46, or by the operation of the forward operator 47, the controller 33 accepts selection of the focused menu, and controls the operations of respective units, as in the menu selection through the touch panel 39. On the other hand, in a case where the back operator 48 is operated through the remote commander 40, similarly to a case where the OFF menu M21 is selected, the controller 33 switches the display to the program menu screen. In this case, the controller 33 switches the display to the remote commander program menu screen.

In the control relating to these menus M21 to M28, in a case where the user selects the list display menu M27, the controller 33 switches the entire display to a list screen as shown in FIG. 6B. Here, this list screen is a list display of content, etc. selectable by the user. A title specifying an application is displayed on an upper part of the screen, and a setting menu M265 to execute various settings relating to this application is displayed on the right corner of the display of this title. In addition, a back menu M261, a cabinet menu M262, a play list menu M263, and a video capsule menu M264 are disposed in sequence on the right side of the screen. Here, the cabinet menu M262 is a menu for instructing so-called list display of folders. Upon the selection of the menu M262, a list of selectable folders is displayed on the list display on the right side. The play list menu M263 is a menu for instructing the list display of selectable content about the currently selected folder through such a list of folders, or the like. By this menu selection, the list of selectable content is displayed on the list display on the right side. The video capsule menu M264 is a menu for instructing display of a thumbnail image about one of the content on the list display.

A region for displaying this thumbnail image is disposed at the center of this list screen. In a case where the video capsule menu M264 is not selected, the content currently played back is displayed at this region.

In addition, menus of a lower hierarchy, which correspond to the menus M261 to M264 of the upper hierarchy disposed on the left side, are displayed on the right side of the display region of this thumbnail image on this list screen. Specifically, there is formed a list display of contents and folders corresponding to the menus M261 to M264 selected by the user. A list, including the menu of content currently played back on this list display, is displayed immediately after displaying this list screen. Here, this list display is to be formed by displaying the titles of respective contents and the names set on a folder on the menu. Therefore, the example of FIG. 6B is the case where this list indicates the list of contents relating to the play list menu M263. In a case where all of the lists of selectable content and folders cannot be displayed at the display region of this list, the controller 33 displays the selectable content and folders by scrolling of this list display, and also indicates by an arrow the direction in which scroll is possible, on the left side of this list. Therefore, in the example of FIG. 6B, upward and downward arrows are provided to indicate that the list of content exists extending beyond above and below the display region.

Also in this case, the controller 33 displays a scroll bar B2 on the right side of this list display, and also displays menus MU, MD for instructing upward and downward scrolls, respectively, on the top and the bottom of the scroll bar B2. Further, the control bar B1 is also displayed on a lower part of the screen on this list screen. In this list, the focused menu is displayed so as to project to the left.

The controller 33 switches list displays and the like by controlling the operations of respective units so as to correspond to the menu selected by the user, in selecting these menus M261 to M265 through the touch panel 39, and the menus of the control bar B1. In other words, if the user selects one of list displays so displayed, by the operation of the touch panel 39, the content to be played back is switched to the user-selected contents, and backs to the original display screen (FIG. 6A). At this time, if the video capsule menu M264 is selected by the user, it displays a still image of the content selected by this user, on the display region for the thumbnail image, and switches the content to be played back to the user-selected contents by the user's operation of the touch panel 39 within this display region, or by selecting again this content through the touch panel 39, and then backs to the original display screen. Similarly, in response to the user's selection through the touch panel 39, it displays the list of content with regard to the folder selected by the user in accordance with the selection of the play list menu M263.

Thus, on this display, the menus of the upper hierarchy and the lower hierarchy are displayed at the same time. Thereby, in the operation through the touch panel 39, it is able to directly select any menu of the upper hierarchy and the lower hierarchy, without tracking the hierarchical structure. On the other hand, in the operation through the remote commander 40, a desired menu can be selected by switching focuses while tracking the hierarchical structure. Therefore, the same menu screens as the touch panel 39 and the remote commander 40 are provided so as to improve usability to the user.

In these processing, when the operation of the scroll bar B2, and the menus MU, MD are detected, the controller 33 causes the list display to be scrolled by this operation. That is, if the menu MU for instructing an upward scroll is operated, the list display is scrolled upwardly. To the contrary, if the menu MD for instructing a downward scroll, the list display is scrolled downwardly. Whereas about the scroll bar B2, a list display is scrolled to the side operated by the operation of dragging.

This enables to reliably select a desired menu even in a case where the menus of the upper hierarchy and the lower hierarchy are displayed at the same time, and all of the menus cannot be displayed. Thus, in the in-vehicle apparatus 1, the size of screen used for display is limited, so that a slight increase in the number of contents causes the cases where all the menus cannot be displayed. Therefore the application to the in-vehicle apparatus 1 enables to improve usability to user.

Thus, with regard to the operation through the remote commander 40, if the center jog 46 of the remote commander 40 is operated with the list screen so displayed, or in a case where the display is switched to this list screen by the operation of the remote commander 40, the controller 33 displays the menu on which the focus is set, by switching a background color in these menus M261 to M265. It also switches focuses by these menus M261 to M265, in response to the rotational operation of the center jog 46. In response to the operation of the forward operator 47, or in response to the press-operation of the center jog 46, it switches the focus to the display relating to the list display, and indicates the focus by similar switching of background colors.

Thus, with the focus set on the list display, the controller 33 switches focuses in sequence in response to the rotational operation of the center jog 46, and scrolls the list display such that the menu so focused is always displayed. In the state of such focusing, in response to the operation of the forward operator 47, or in response to the press-operation of the center jog 46, the controller 33 accepts the selection of content and folder by the user, and switches the playback target to the selected content, and switches the folder as a selection target. To the contrary, when the back operator 48 is operated, it switches the setting of focuses to the menus M261 to M265.

Accordingly, the in-vehicle apparatus 1 is configured such that desired content can be selected and viewed from video content stored in the hard disk drive 35 by the operation of the touch panel 39, or by the operation of the remote commander 40.

In the in-vehicle apparatus 1, various setting screens are displayed by the selection of the setting menu M265 set on the screen of FIG. 6B, or by the setting through the menu screen displayed by the operation of the menu operators 15R, 15P. It is settable so as not to display the control bar B1 by the operation of the menu set on this setting screen. Alternatively, it is also settable so as not to display the control bar B1 by the operation of the menu M28 shown in FIG. 6A.

FIG. 7A is a front view showing a main display screen in a case where it is configured so as not to display the control bar B1, in contrast to FIG. 6A. When the operation of the touch panel 39 is detected in a condition that the control bar B1 is not displayed, a control bar B11 is displayed, as shown in FIG. 7B. Thereby, in displaying attribute information as information related to images, the in-vehicle apparatus 1 is configured so as not to display it for a time period during which the attribute information is not required, but display it only when necessary, at a corner of the screen. This effectively avoids complexity of display in order to provide a user interface relating to a simple display.

By setting the timing of displaying such information related to images at the timing corresponding to the operation of the user, it is able to provide this attribute information to the user at his/her desired timing, thereby improving usability to user.

Here, the control bar B11 is, in contrast to the corresponding control bar B1 (FIG. 6A), configured so as not to display the menus M21 to M27, which are the OFF menu M21, and the menus of the rewind, the back-to-previous chapter, the switching of playback/pause, the forward-to-next chapter, the fast forward, and the list display. However, display the title of content, and the switching menu M28 for switching display/non-display of the control bar B11.

In a case where no operation of user is detected after an elapse of a certain period of time since the display of the control bar B11 is so started, or when the switching menu M28 is operated to close the display window, the controller 33 terminates the display of the control bar B11 and displays the original screen (FIG. 7A). Thereby, in the in-vehicle apparatus 1, the menus relating to the operations of the touch panel 39 and the remote commander 40 are retreated from the display screen 11 when they are not required, and content are displayed in order to effectively use the display screen 11.

On the other hand, when the operation on a portion other than the switching menu M28 to close the display window of the control bar B11 is detected, the controller 33 displays the menus M21 to M27, which have been hidden from the display screen. The display changes at this time are as shown in FIGS. 7C to 7E. Gradually from the left end of the menu M28, the menus M22 to M27 are removed and displayed to the center, in order to display these menus M22 to M27, as if the menus M22 to M27 hidden under the menu M28 appeared and moved to a visible position. When the menus M22 to M27 are displayed in this way and the display region for titles is not enough, the titles are scrolled to be displayed. The operation of the user is accepted with the menus M21 to M28 displayed in this way.

Thereby, in the in-vehicle apparatus 1, with regard to the display of the control bar B11, the display of menus is switched between a state of overlapping a plurality of menus and a state of arranging the overlapped menus, so that the region for displaying attribute information and the region for displaying the plurality of menus are variable. This also enables that the attribute information and the menus are suitably displayed so as to be user-friendly, in order to simplify the display.

When the center jog 46 of the remote commander 40 is operated with the control bar B1 so set in the non-display state, the controller 33 displays the control bar B11 displaying all the menus M21 to M28. Also in this case, if no operation of the user is detected after a certain period of time has passed since the display was started, or if the switching menu M28 is operated to close the display window, the controller 33 terminates this display of the control bar B11. With the control bar B11 displayed, the focus is displayed to accept the operation through the remote commander 40, as in a case of regularly displaying the control bar B11.

In a case where the menu M1 for instructing viewing and listening of television broadcasts is selected on the program menu screen, the controller 33 displays contents, the control bar, and the like, in accordance with the record of the last memory, as above described with reference to FIG. 6A to FIG. 7B, and also switches the contents relating to the broadcasts, in response to the operation of user. Therefore, in this case, a menu for instructing up and down of the channels, a menu for instructing the display of a list of contents that can be viewed on an electronic program table, and the like are displayed at the control bar, together with the titles of contents. In addition, with regard to selectable contents, a list of programs is provided which is based on the electronic program table obtained via the communication unit 34.

Also in this display relating to the television broadcasts, the controller 33 displays the control bar display/non-display menu. By the selection of this menu, or by the operation of the menu set on this menu screen, it is settable so as not to display the control bar. It accepts the operation of user by setting so as not to display the control bar and displaying contents, alternatively, as above described with reference to FIG. 7A to FIG. 7E, the control bar is displayed by the operation of the touch panel 39 or the operation of the remote commander 40, or by displaying the menus. Thus, in the in-vehicle apparatus 1, even in a case of providing the content of television broadcasts, the menus relating to the operations of the touch panel 39 and the remote commander 40 are retreated from the display screen 11, and contents are displayed so as to effectively use the display screen 11.

FIG. 8 is a plan view showing a main display screen of music content relating to the menu M3 on the program menu screen. By the selection of the menus M3, M3R, the controller 33 plays back music content recorded in the hard disk drive 35 in accordance with the record of the last memory, and provides it to the user. At this time, the controller 33 displays this display screen shown in FIG. 8.

In this case, the controller 33 displays a title indicating music content provision, at a strip portion on the upper side of the display screen. Further, a back menu M31, a title menu M32, a genre menu M33, an artist menu M34, a play list menu M35, and an album menu M36 are disposed in sequence on the left side of the screen. Here, the music content recorded in the hard disk drive 35 is recorded so that it can be classified by title, genre, artist, play list, and album. In accordance with this classification, the controller 33 displays a list of the music content recorded in the hard disk drive 35 at a list display column on the right side, in response to user's selection of the menus M32 to M36.

On this display screen, a display column of an artist name, an album name, etc., relating to such selection is formed at the center, and a list of providable content relating to each classification is displayed on the next right column. In a case where all of selectable content cannot be displayed on the display region of this list, the controller 33 displays the selectable content by scrolling of this list display, and also indicates by the arrow the direction in which scroll is possible, on the left side of this list. Therefore, in the example of FIG. 8, upward and downward arrows are provided to indicate that the list of contents exists extending beyond above and below the display region. Also in this case, the controller 33 displays the scroll bar B2 on the right side of this list display, and also displays menus BU, BD for instructing upward and downward scrolls, respectively, on the top and the bottom of the scroll bar B2. Further, the control bar B1 is also displayed on a lower part of the screen on this list screen. In this list, the focused menu is displayed so as to project to the left.

By the operation of these menus M31 to M36 through the touch panel 39, and the operation of the list display control bar B1, the controller 33 switches content as a playback target so as to correspond to the selection operation of user, in the same manner as above described with reference to FIGS. 6A-6B, and FIGS. 7A-7E. Also in this case, the upper hierarchical menus and the lower hierarchical menus are displayed at the same time, so that the operations through the touch panel 39 and the remote commander 40 are accepted. When the operations of the scroll bar B2, and the menus MU, MD are detected, the controller 33 scrolls the list display in accordance with this operation. Therefore, in a case where the menus of a plurality of hierarchies are displayed at the same time and all of the menus cannot be displayed, the menus that cannot be displayed are displayed by scroll.

Further on this display screen, a visualizer menu for switching a wall paper composed of animated images, which is displayed at the display region of artist names, a menu for instructing shuffle playback, and a menu for instructing repetitive playback are disposed in sequence on the left end of the control bar B1. The menus of rewind, back-to-previous-title, pause/regeneration, forward-to-next-title, fast forward, list, control bar display/non-display are displayed in sequence on the right side.

Thus, immediately after displaying this display screen, the controller 33 displays, with regard to the music content currently provided to user, a list of content relating to the album being played back. By the operation of the list menu disposed at the control bar B1, the display of the above-mentioned list display column can be switched from the list display of titles currently played back to a list display of providable contents. In response to this display switching, the focus is switched from the menus of the control bar B1 to the menus M31 to M36, with respect to the operation of the remote commander 40. Thereby, the menus of three hierarchies, including the control bar B1, are displayed on this display screen of the music content.

Thus, relating to the control bar B1, the controller 33 is configured to accept the operations through the touch panel 39 and the remote commander 40, and switch the entire operation in the same manner as described above. As a result, in this case, the menus of the three hierarchies are directly selectable in the operation through the touch panel 39.

On the other hand, FIG. 9 is a plan view showing a main display screen of a map. When the menu M4 relating to maps is selected on the program menu screen, the controller 33 displays a peripheral map of the current position. It also displays information D1 related to this map display at a strip region on the upper end of the screen. Alternatively, when the user previously instructed navigation processing, the controller 33 displays information relating to the navigation, together with this strip region.

In this previous setting, a menu screen shown in FIG. 10 is displayed and executed by the operations of the menu operator 15P disposed on the panel, and the menu operator 15R disposed at the remote commander 40. On this display screen, a destination input menu that is the menu of the uppermost hierarchy in the menus relating to navigation, and the like are displayed on the right side. The menus of a lower hierarchy selected from the menus on the left side are displayed at the center, and the menus of a further lower hierarchy are displayed on the rightmost end. FIG. 9 shows the state in which a place menu is selected on the menus of this upper hierarchy, and then a genre menu corresponding to this place menu is selected.

The controller 33 is configured to accept the input of a destination by the selection of the menus in this hierarchical structure, and execute processing of a route search from the current position to the destination, and guide the user in accordance with this route. Also in this case, the menus of the three hierarchies are displayed at the same time. Therefore, for example, if user erroneously selects the genre menu, it is configured so as to directly select the menus of peripheral facilities search and the like, depending on the operation of the touch panel 39. On the other hand, in a case with the remote commander 40, it is configured such that a desired menu is selectable by switching focuses in sequence and tracking the hierarchical structure.

In the in-vehicle apparatus 1, the above-mentioned control bar display/non-display can be set per menu of the menus M1 to M8, as well as split ratio on two-screen display to be described later, by the operation of the setting menus on this display screen.

The display screen of FIG. 9 is a display screen when the navigation processing is executed under such setting. Although in the example of FIG. 9, the surroundings of the current position are displayed by map, various displays such as display in the form of birds-eye view, etc. are selectable on this display.

When the information D1 relating to the display of maps is displayed as described above, and the display relating to scale is operated through the operation of the touch panel 39, the controller 33 displays the menu of switchable scales, the menu of wide area, and the menu of details, as shown in FIG. 11, and switches the scale of map display when the scale menu is selected through the operation of the touch panel 39. Alternatively, if the menu of wide area or the menu of details is selected, the scale of map display is switched stepwise in sequence, in accordance with the setting of this scale menu. Relating to this, when the zoom-up and zoom-down operator 42 is operated through the remote commander 40, in the state of displaying the menus such as scales, or in the state of not displaying the menus such as scales, the controller 33 switches the scales of map display stepwise in sequence, in the same manner as the case where the menu of wide area or the menu of details is selected, respectively.

Alternatively, if the user touches with his/her finger on a map display through the operation of the touch panel 39, the map display is moved such that the finger-touched portion becomes the center of the map. Alternatively, if the joystick 43 is operated in the remote commander 40, the map is scrolled in the direction of operation of the joystick 43. Alternatively, when the current position operator 44 is operated in the remote commander 40, the display of the map is switched such that the current position is located at the center of the screen. Accordingly, the in-vehicle apparatus 1 is configured such that the map display can be switched variously through the remote commander 40 or through the touch panel 39.

In the in-vehicle apparatus 1, on the display screen relating to this map display, the display of the information D1 relating to the map display is terminated by the setting on the menu screen as above described with reference to FIG. 10. Thus, by configuring so as not to display the information D1 relating to the map display, in the navigation processing, the information D1 related to the map display is displayed at the timing with reference to a guide point that is a reference point used in route guide, as shown in FIG. 12A to FIG. 12D, and voice guide is provided to the user at a predetermined timing. Specifically, this timing is, for example, timing prior to a predetermined time at which the arrival of the guide point is forecasted. Also in this case, the controller 33 provides the user various information by gradually switching displays, as if the display of the information D1, which has been hidden till then on the outside of the display screen, appeared on the display screen 11, as indicated by the changes at the time of starting the display in the order of FIG. 12A to FIG. 12D.

Alternatively, the information D1 relating to the map display is usually not displayed, and the information D1 is displayed when the user operation relating to the region displaying the information D1 is detected with the touch panel 39.

Therefore, also in this case, the in-vehicle apparatus 1 is configured such that the displayable region is effectively used to provide the user the information relating to maps.

On the other hand, the main display screen relating to the AUX input menu M5 is formed according to the content relating to the AUX input, in the same manner as the above-mentioned display screen relating to the viewing of video content and the above-mentioned display screen relating to the listening to music content, which are recorded in the hard disk drive 35. Also in this case, the display screen 11 is effectively used in order to prevent deterioration of usability to user, by configuring such that the control bar B1 is not displayed as required, or displayed as required.

On the other hand, the main display screen relating to the Internet menu M6 is formed by displaying web pages and the like, together with the menus of forward, back, and the like. The display screen relating to the electronic mail menu M7 is formed by displaying the menus of receive mails, sending mails, mail creation, and the like. It is configured such that contents are displayed by the selection of each mail, or a mail creation screen and the like are displayed. The main display screen of the menu M8 relating to still images is formed by displaying a menu for operation relating to still images, together with the thumbnail images of respective still images. By the selection of the thumbnail image, the corresponding still image is displayed in an enlarged scale. Alternatively, the selection of the menu enables to execute the display of a slide show, and the like.

Also on these display screens, the controller 33 is configured to accept selection of the menu by the operation through the touch panel 39 and the operation through the remote commander 40, and further accept display switching and the like.

In selecting the menus M1 to M8 through this program menu screen, when a menu other than the menus M1 to M3 for providing contents is selected by user, under conditions where contents is being provided to the user by any one of sources, the controller 33 continues to execute provision of the contents and raise processing relating to the menu selected by the user. This enables the in-vehicle apparatus 1 to execute processing of checking electronic mails or the like, while enjoying music, for example.

On the other hand, in selecting the menus M1 to M8 through this program menu screen, when other menu for providing contents is selected, under a condition where content is being provided to the user by any one of sources, the controller 33 suspends providing of the content provided to the user until then, and plays back the content selected by the user. Thereby, in the in-vehicle apparatus 1, the source relating to this contents can be switched by displaying the program as above described with reference to FIG. 4 or FIG. 5, and selecting the menus M1 to M3.

Even by the press-operation of the source operator 13P disposed on the control panel, or the source operator 13R disposed at the remote commander 40, instead of the operation through this program menu screen, the controller 33 starts the operation of the corresponding application and also switches the application, as in a case where the menus M1 to M3 relating the source of content are operated.

In other words, the controller 33 starts the operations of respective units in the same state as the time of turning power down, by the user's operation of the power switch 12. When this state is the state where content is provided to the user by the application of any one of the menus M1 to M3, the controller 33 switches sequentially and cyclically the source provided to the user, in response to the operation of the source operators 13P, 13R, as indicated by an arrow A in FIG. 13. In FIG. 13, “Audio” and “Video”, denote the applications relating to music content and video content recorded in the hard disk drive 35, respectively, and “TV” denotes the application relating to television broadcasts.

On the other hand, when the operations of respective units are started in the same state as the time of turning power down, and this state is not caused by the application relating to the menus M1 to M3, the most recently used application is restarted in accordance with the record of so-called last memory, in a state at the point where the use is suspended. Also in this case, the display relating to the started application is preferentially displayed on the display screen 11. Therefore, as indicated by an arrow B in FIG. 13, when the source operators 13P, 13R are operated with no content provided, and with a map displayed, the controller 33 is configured to switch the display of the map to the display relating to content, and start to provide the content.

Thereby, in the in-vehicle apparatus 1, desired contents can be selected easily by only repeatedly doing press-operation of the source operators 13P, 13R, so that usability is improved to that extent.

On the other hand, when the map controller 17P disposed on the control panel, and the map operator 17R disposed in the remote commander 40 are operated under a condition where certain content is provided to user, the controller 33 starts the application relating to the menu M4, and switches the display of the display screen 11 to the display of a map, as indicated by an arrow C in FIG. 13. Thereby, in the in-vehicle apparatus 1, the present position and the like can be confirmed easily only by operating the map operators 17P, 17R, under a condition of enjoying video content by television broadcasts, video content and music content recorded in the hard disk drive 35.

Thus, the controller 33 displays a map by the operation of the map operators 17P, 17R, and switches the display of the display screen 11 to the display of content when the map operators 17P, 17R are operated again. Thereby, in the in-vehicle apparatus 1, repetitive operation of the map operators 17P, 17R enables to switch between display/non-display of a map. This also permits to improve usability.

In the display switching by the map operators 17P, 17R, and the display switching by the source operators 13P, 13R, it is set so as to transit, for example, from a lower hierarchical screen relating to the display of lists and the like, not only from a state where the main display screen of each application is displayed. This also permits to improve usability in urgent confirmation of the current position and the like.

The controller 33 also switches displays between the application relating to provision of content and the application of maps, when the user operates the display operators 16P, 16R, which are operators for switching displays. At this time, if no contents is being provided to the user, it starts the most recently used application relating to provision of contents, in accordance with the record of the last memory, and switches displays.

As shown in FIG. 14B, at this time, while a two-screen display, in which the displays relating to two applications are aligned and displayed concurrently, is interposed by the previous setting with use of the menu screen (FIG. 10), it switches the displays sequentially and cyclically by the operation of the display operators 16P, 16R. In the application of the menu M3 relating to provision of music content, the display of such a two-screen display is omitted because this is not provision of content composed of images. Thereby, in the in-vehicle apparatus 1, the processing of checking a map relating to navigation, and the like is executable, while checking, for example, the running commentary of television broadcasts by merely switching the display screen 11.

As shown in FIG. 14A, in a case where two-screen display is instructed by the user, when the display operators 16P, 16R is press-operated by the user, for example, under a condition where a map is displayed, the controller 33 switches the display of the display screen 11 to two-screen display, and reduces the image relating to provision of content on the right side, and displays the map at the remaining region on the left side. Subsequently, when the user operates the display operators 16P, 16R, the controllers 33 switches the two-screen display to contents provision screen, as shown in FIG. 14C. It is configured to display the original map display screen when the user further operates the display operators 16P, 16R.

On the other hand, in a case where user does not instruct two-screen display, the controller 33 skips two-screen display, and switches between the display of a map and the display of contents, in response to the operation of the display operators 16P, 16R.

In the two-screen display displayed in this way, the controller 33 sets the display size of each screen in accordance with the division ratio previously set using the menu screen (FIG. 10). This enables to execute concurrently the displays of such two applications, thereby improving usability to the user.

FIG. 15 is a plan view showing a display screen at the time of switching displays between a map and content. This display is applicable to a map screen, a content provision screen, and a two-screen display, when the display is switched between a map and a contents provision screen, by the operation through the source operators 13P, 13R, and the map operators 17P, 17R, as described above with reference to FIG. 13, and the display operators 16P, 16R as described above with reference to FIG. 14A to FIG. 14C. The example shown in FIG. 15 is a case to which the content provision screen is applied.

The controller 33 displays the information D1 related to the map display and the control bar B1 relating to provision of content, at upper and lower ends on this display, respectively. Thereby, in the in-vehicle apparatus 1, it is able to check a variety of information related to the current position and navigation, even while viewing content, for example. As described above with reference to FIGS. 6A and 6B, etc., the operations of the menus through the control bar B1, the touch panel 39 relating to the display of the information D1 related to map display, and the remote commander 40, are accepted in the same manner as in the case of separately starting applications.

On the other hand, in a case where non-display of the control bar B1 and the information D1 related to map display are selected by the setting by the user, when the region for displaying the information D1 related to map display is operated through the touch panel 39, the controller 33 displays the information D1. To the contrary, when the control bar B1 side is operated through the touch panel 39, it displays the control bar B1. Additionally, various operations by the user are accepted via this display. Here, the transitions from the non-display state to the display of the control bar B1 and the information D1 related to map display are carried out in the same manner as described above with reference to FIGS. 7A-7E, FIGS. 12A-12D, respectively.

On the other hand, in the operation through the remote commander 40, it displays concurrently the control bar B1 and the information D1 related to map display by the operation of the center jog 46, and switches focuses between the display of the control bar B1 and the display of the information D1 related to map display, in response to the operation of the center jog 46.

Thereby, even when executing two applications at the same time, the displayable region of the display screen 11 is effectively used so as to accept the operation of the user in the in-vehicle apparatus 1. The example shown in FIG. 15 is a case of mainly displaying the aforesaid other application side under conditions where the map application and other application are being executed concurrently. In a case of displaying the map side, or in a case of two-screen display, the control relating to the displays of the control bar B1, and the information D1 related to map display is executed similarly.

Even if the operation is terminated by any operation of the user, with regard to the respective applications corresponding to the menus M1 to M8, the controller 33 records and holds, per application, the state when the operation terminates. In the activation of each application, it reproduces the state immediately before termination, in accordance with this record. Specifically, with regard to the applications of the menus M1 to M3 relating to contents provision, the controller 33 records the most recently played back file name, and the position at which the playback is suspended, per application (i.e., per source, in this case). With regard to the source relating to video content, there is recorded as to whether it was two-screen display or not, and whether the control bar B1 was in non-display or not, and whether it was the main screen or the list screen, at the point of time that the content provision was suspended.

When switching sources sequentially and cyclically by the above-mentioned operation of the source operator, the controller 33 displays, for example, the content of television broadcasts by two-screen display, by starting each application in accordance with this record. In this state, when the user operates the source operator, it displays the video content recorded in the hard disk drive 35, on the overall of the display screen, and the like. Thus, even in switching sources sequentially and cyclically, it is configured so as to perform image display in the form to meet the preference of user. Accordingly, in this case, the control bar B1 is to be displayed or not displayed, per content. Depending on the content, the list screen is to be displayed.

With regard to a specific operation among various operations relating to such display, which are assigned to the center jog 46, the controller 33 also accepts the operation through a side jog 52. Specifically, the controller 33 accepts, through the side jog 52, the operation relating to contents provision among the operations accepted through the center jog 46. Additionally, it accepts the operation of the source-off operator 54, and the back operator 53, which are disposed on the side surface in relation with the side jog 52, together with the side jog 52. Here, the source-off operator 54 is an operator for instructing the termination of the contents-related application in the course of drive. The back operator 53 is an operator for instructing the same operation as the back operator 48 disposed next to the center jog 46.

Thereby, in the in-vehicle apparatus 1, the operation relating to specific contents provision can be operated with the controllers disposed on the side surface of the remote commander 40, by so-called blind touch, so that usability is improved to that extent.

Specifically, when the side jog 52 is rotationally operated in a case of providing music content to the user, the controller 33 executes processing of so-called title skipping in the direction in which the side jog 52 is rotationally operated. Alternatively, when the side jog 52 is press-operated, it switches the display to the list screen. In this state, it switches focuses and accepts the selection of content by the user, by the operation of the side jog 52, and then switches the display to the original screen by the operation of the back operator 53.

On the other hand, in providing content by television broadcasts, it switches the receiving channel by the rotational operation of the side jog 52. In providing video content recorded in the hard disk drive 35, it executes skip processing in the direction of operation in the units of predetermined time, by the rotational operation of the side jog 52.

(2) Operation in Preferred Embodiment

With the foregoing configuration, by mounting the in-vehicle apparatus 1 (FIG. 1 and FIG. 2) on the in-vehicle cradle 2A disposed in a vehicle, it receives the supply of power from the vehicle, and is connected to the external unit 21, and a car audio system 28, etc., which are disposed in the vehicle, thereby making possible to use in the vehicle. In the in-vehicle apparatus 1, by the operation of the power switch 12, the power is turned on so as to permit to use for navigation, and enjoy music and video content, and content by television broadcasts, further check the current position.

In the in-vehicle apparatus 1 that is so used for enjoying contents and checking the current position and the like, the program menu screen that is a menu of available applications is displayed (FIG. 4, FIG. 5) by the operation of the remote commander 40 (FIGS. 3A-3C), or the operation of the touch panel 39 disposed on the display screen 11. A desired application is activated by the selection of the menu on this program menu screen. This enables to enjoy, for example, the content by television broadcasts. This also enables to start a plurality of applications and display, for example, a map in order to check the current position, while enjoying music, for example.

On the main display screen of each application so displayed by selecting the application, a menu toward the list screen relating to the selection of content, and the like are displayed, or various menus relating to the playback of content, and the like are displayed. Then, by the operation of the touch panel 39, or the operation of the remote commander 40, various operations, such as switching of content by selecting these menus, are executable (FIG. 6 to FIG. 12).

Thus, in such a series of operations, by the operation of user relating to the transition to the program menu screen in the in-vehicle apparatus 1, the touch panel menu screen (FIG. 4) suitable for the operation through the touch panel 39, and the remote commander menu screen (FIG. 5) suitable for the operation through the remote commander 40 are switched and provided to the user.

Thus, in selecting a menu through the touch panel 39, and in selecting a menu through the remote commander 40, an appropriate user interface corresponding to the operation target is provided to the user, thereby improving usability.

Specifically, the user is able to operate the in-vehicle apparatus 1 using either of the remote commander 40 or the touch panel 39. This enables to select operating means suitable for the user's situations, for example, in a case where the user himself/herself is driving, or in a case where the user sits on the rear seat, and select an application on the menu screen suitable for the operating means. This makes possible to reduce the burden of passengers under use situations.

In addition, on the touch panel menu screen and the remote commander menu screen, the corresponding menu screen is provided by the operation of the user, which is a trigger of transition, when the user intends to select a menu by the operation of the touch panel, and when the user intends to select a menu by the operation of the remote commander, respectively.

That is, if the operation relating to the transition to the program menu screen is the operation of the operator on the display panel or the operation of the touch panel, it can be judged that the user relating to this operation for transition is seated at the front seat and he/she intends to select a menu by the operation of the touch panel. Therefore, in this case, the program menu screen for touch panel is provided. Alternatively, if the operation relating to the transition to the program menu screen is the operation of the remote commander, it can be judged that the user is seated at the rear seat, for example, and he/she intends to select a menu by the operation of the remote commander. In this case, the menu screen for remote commander is provided. Thereby, the in-vehicle apparatus 1 permits to improve usability to the user in accepting the operations through the touch panel and the remote commander.

Even when the menu screen is provided by judging the intention of user as described above, there can be considered, for example, a case where a user different from the user relating to the operation for transition selects a menu, or a case of directly operating on the display of the program menu screen. Hence, in the in-vehicle apparatus 1, also in the remote commander menu screen, a menu selection through the touch panel 39 is acceptable, thereby improving usability to the user. Alternatively, the display of the remote commander program menu screen can be switched to the touch panel program menu screen by the operation through the touch panel at a portion other than the menus. To the contrary, the touch panel program menu screen can be switched to the remote commander program menu screen by the operation of the remote commander. This enables to provide the menu screen that exactly reflects the intention of the user, thereby further improving usability to the user.

Thus, in the in-vehicle apparatus 1, this touch panel menu screen is formed by displaying a plurality of menus at the same size, thereby providing the menu screen suitable for operation, to the touch panel on which it is able to directly operate any menu.

On the other hand, the remote commander 40 is one in which selection is made by setting a focus, and therefore in the in-vehicle apparatus 1, the remote commander menu screen is a screen on which a plurality of menus are displayed to visibly confirm a focused menu, and the focus can be switched by the operation of the remote commander, so that the menu screen suitable for the operation of the remote commander is provided.

(3) Effects of Preferred Embodiment

With the foregoing configuration, in a case of accepting the operation through the touch panel and the remote commander by switching and displaying the touch panel menu screen suitable for the operation through the touch panel, and the remote commander menu screen suitable for the operation through the remote commander to accept the operation by the user, usability to the user can be improved.

Additionally, the menu screen specifically suitable for the operation through the touch panel can be provided by the feature that the touch panel menu screen is a screen on which a plurality of menus are displayed at the same size.

Additionally, the menu screen specifically suitable for the operation through the remote commander can be provided by the feature that the remote commander menu screen is a screen on which a plurality of menus are displayed to visibly confirm a focused menu, and by switching focuses through the operation of the remote commander.

Additionally, by accepting a menu selection through the touch panel on the remote commander menu screen, a desired menu is selectable by direct operation through the touch panel, irrespective of the menu selection by the operation of the remote commander, and the flow of operation for decision. This improves usability to the user.

It is also able to exactly understand the intention of the operation by the user and provide the menu screen suitable for the operation, by executing, through the operation of the remote commander, the switching from the touch panel menu screen to the remote commander menu screen, and executing, through the operation of the touch panel, the switching from remote commander menu screen for remote commander to the touch panel menu screen.
